  • What we do.

    Here to help, for everything RO.

    Cost-effective consumables

    We source globally and supply plants across Australia with high-quality, cost-effective RO consumables.

    With careful technical consideration of your application, we'll help identify cost-savings and select the right filters, chemicals, antiscalants and membranes for reliable performance.

    Feed-water ch​emical analysis

    Using powerful modelling software we perform thermodynamic aqueous equilibrium analysis to understand your exact feed-water chemistry speciation and accurately simulate plant operation.

     

    We then develop and recommend strategies for effective pre-treatment, chemical dosing, antiscalant and cleaning to maximise plant performance and stability.

    Plant & site optimisation

    Tune your RO plant to its best. We conduct comprehensive, detailed reviews of site water balance and RO plant operation. We work closely with specialised water analysis and membrane autopsy labs to understand complex fouling situations and root cause.

     

    With comprehensive feed, membrane, energy and cost modelling we'll help you make changes to pre-treatment, chemical dosing and plant configuration to maximise performance and extend membrane life.
